The purpose of this study was to determine the effects of a twelve-week aerobic training program on the body composition of overweight or obese young men. The sample consisted of 21 males of 21.86 ± 1.85 years old. The training was carried out for twelve weeks, running it 3 times a week for a period of 60 to 90 minutes. Before and after the program, their weight, height, body mass index, percentage of lean mass, percentage of fat mass through bone densitometry were evaluated. It's concluded that the aerobic training of twelve weeks of duration in young men with overweight or obesity produces improvements in the studied parameters, being able to influence with this in the improvement of the health and quality of life of these population.

The aim of this study was to determine whether a rowing training program could improve cardiac function in women (n = 28) with the mean age of 52.30 ± 3.78 years who survived breast cancer (stage 1: 4.55%; 2: 36.36%; 3: 54.54%; and 4: 4.55%) diagnosed 4.68 ± 3.00 years previously and underwent subsequent surgery (preservation: 56.52%; total mastectomy: 39.13%; and double mastectomy: 4.35%). Participants completed a 12-week training program consisting of three weekly sessions lasting 60–90 min with a progressive intensity increase according to the Börg scale. The assessments performed were blood pressure and pulse measurements both at rest and after performing the six-minute walk test to collect data on cardiac behavior and aerobic performance. The results showed statistically significant differences in cardiovascular system efficiency measured on the basis of heart rate both before (−12.63 ± 14.68 bpm) and after the six-minute walk test (−11.46 ± 28.39 bpm), increase in the distance achieved in the aerobic endurance test (51.56 ± 48.26 m) as well as decrease in diastolic (−13.6 ± 7.85 mm Hg) and systolic (−6.60 ± 9.10 mm Hg) blood pressure. These results suggest that rowing training programs could be a strategy to consider in this population for the benefits observed in heart rate, blood pressure and aerobic performance, which would lead to improved general health and quality of life.
